Halo: Spartan Strike, a sequel to last year's twin-stick shooter Halo: Spartan Assault, has been announced for Windows 8 devices and PC by Microsoft.

As before, you'll battle a horde of familiar enemies from the Halo universe in a top-down, twin-stick mode. This time around you'll also get new vehicles and abilities, and 30 new missions to complete.

Well well, look what the Grunts dragged in. Microsoft has announced top-down twin-stick shooter Halo: Spartan Assault is finally coming to PC Steam. Until now it has been exclusive to Windows 8, consoles and phones.

Apparently this 'Steam' platform is a big deal or something, which is odd from Microsoft's view as they don't own it, so how could it be important? They're willing to humour this 'Steam' April 4th.
